Perenise makes up a dynamic front-row with Nathan Catt and Rob Webber, as Dominic Day takes his place at second-row alongside captain Stuart Hooper. Guy Mercer comes onto the openside flank, joined by the powerful duo of Matt Garvey and Leroy Houston to complete the pack.

Peter Stringer combines with George Ford in the half-backs and Jonathan Joseph resumes his midfield partnership with Kyle Eastmond. The potent duo of Matt Banahan and Semesa Rokoduguni line up on the wings, as the elusive Nick Abendanon starts at full-back.

Meanwhile, there is only one change to the London Wasps squad that recorded a bonus-point win against Gloucester in "The Stinger" at Twickenham last weekend.

Phil Swainston starts at tighthead in place of Jake Cooper-Woolley, who is ruled out through injury. Taione Vea comes onto the bench.
